The set of integers is closed under the operation of addition.
A: Which equation illustrates this concept?
B: Which statement correctly explains this concept?
Select one answer for question A and one answer for question B.
A: 2+27=29
A: 34:4=172
A: 1-3=-2
A: 2⋅6=12
B: The sum of the integers 2 and 27 is the integer 29, which demonstrates that integers are closed under addition.
B: The quotient of the integers 34 and 4 is the integer 172, which demonstrates that integers are closed under addition.
B: The difference of the integers 1 and 3 is not an integer, - 2, which does not demonstrate that integers are closed under addition.
B: The product of the integers 2 and 6 is not an integer, 12, which does not demonstrate that integers are closed under addition.
